MOP-WRINGER.

SPECIFICATION forming part of Letters Patent No. 480,192, dated August2, 1892.

Application filed October 19, 1891- Serial No. 409,180. (No model.)

To aZZ whom it may concern:

Be it known that I, ALFRED H. I'IAFER, a citizen of the United States,and a resident of Cleveland, county of (luyahoga, State of Ohio, haveinvented certain new and useful Improvements in Mop-VVringers, of whichI hereby declare the following to be a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in portable mop-wringers adapted tomount upon pails, and its objects are to provide a powerful leverage toforce the wringing-rollers into contact and also to so place theportions which become in tension when the mop is withdrawn that a directresistance will be obtained and there will be no danger of overturningthe pail and water.

My invention consists in the use of a stationary roller secured near oneedge of the pail and a movable roller secured to a powerful leverpivoted upon the sides of the pail, and in the details of constructionand arrangement as herein described, shown in the accompanying drawings,and more specifically set forth in the'claims.

In the accompanying drawings, Figure l is a side elevation of a bucketwith the improved wringer attached. Fig. 2 is a plan of the bucket andattached wringer. Fig. 3 shows a preferable form of rollers inelevation. Fig. 4 is a plan of same.

In the drawings, A is the bucket.

B is a roller mounted horizontally across the top of the bucket upon themetal strap 0, which rests upon the edge of the bucket at theextremities c and connects the two bearings for the roller by a strap 0,crossing the side of the bucket at one side of the roller. A verticalcontinuation of the strap O on either side of the bucket is secured byone or more screws 0 to the bucket.

D is a long bell-crank lever pivoted near the central portion of thebucket upon the strap 0 on either side, The arms of the bellcrank extendupwardly, and in the extremity of the shorter arm is pivoted the rollerD, somewhat larger than the roller B, while the longer arm projectsoutside of thebucket and is connected from one side to the other by thefoot-tread d, by which it is operated. Springs E, connecting the lever Dand strap 0 in front of the pivoted point (1, return the lever whendepressed. A prop F, attached at f to the bucket and at f to the strap0', serves to take the outward thrust of the bucket when pulling the mopbetween the rollers and prevent upsetting it.

It will readily be seen that a very high degree of positive pressure canbe obtained by use of the lever D and pressure of the foot placed uponthe tread (1', while the position of the stationary roller B is suchthat all pull upon the mop when under pressure in the rollers isdirectly transmitted to the tread and offset F by the Weight of thefoot, so that a perfect equilibrium is maintained when in use. Inaddition to this the enlarged size of one of the rollers D gives anadditional radial leverage in withdrawing the mop, while the smallerroller 13 receives the pressure and drains the mop.

The advantages of the device are obvious in the improved pressure andperfect balance of the parts, as well as in the simplicity and slightinitial cost of the parts.

In Fig. 2 in dotted lines is shown a modified form, where the diametersof both rollers are enlarged. The side strap 0 is extended at Orearwardly in front of the roller 13 on each side to serve as a guide tothe mop in entering the rollers, and the extremities of the extensions 0abut against the enlarged ends of the rollers.

In Fig. 1, f is a stop to prevent excessive pressure upon the rollers.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In a mop-wringer, a stationary roller secured to a removable supportnear the edge of a bucket, a movable roller mounted upon the shorter armof a foot-lever, also secured to said removable support and adapted tobe brought into engagement with the stationary roller by the movement ofthe lever, and a projecting prop secured to said support in closeproximity to the pedal extremity of the lever, substantially asdescribed.

2. Inamop vringel',vertical straps detachenlarged central portion of theroller from ably secured to the side of a bucket and conend extremitiesof lesser diameter, substannected above the pail by a horizontal straptially as described. resting therein, bearings on side extensions ALFREDII. HAFER.
